A method of manufacturing a porous body using particulate material as a starting stock. The particles are inserted in a can, the can evacuated and inert gas admitted to a predetermined back-fill pressure. After hot isostatic pressing, the compact so formed is cooled and subsequently heat treated to permit the pores formed in pressing to expand and form a porous body.

A warp-knit tape (10) for hook-and-loop fasteners comprises a pile portion (11) and selvage portions (12) extending on opposite longitudinal edges thereof, the pile portion (11) being constructed with pile threads (14), foundation threads (15) and laid-in weft threads (16). The pile threads (14) are knitted into a continuous chain of pile loops (P) each having a rise portion (P') and a horizontall...

The invention relates to structures and/or devices which are in an intimate tissue contact or are installable at least partly to the inside of tissues and/or organs and/or body cavities (ducts), and which have some function (especially core layer II), such as the supporting and/or joining and/or replacing of tissues and/or organs or parts thereof, and/or the conveying of material and/or energy bet...

A release agent composition which manifests almost no silicone migration and a very low slickness while nevertheless having a low release value is achieved by means of a release agent composition which is based on a methylalkenylpolysiloxane, an alkylhydrogenpolysiloxane crosslinker for the methylalkenylpolysiloxane, an organopolysiloxane containing monovalent hydrocarbon groups which lacks alipha...

A washing-apparatus, preferably a dish-washer, has a container (1) with baskets (2,3) for the articles to be washed up or cleaned, a flushing system with a circulation pump (8), spray arms (4,5), a strainer system with a fine strainer (15) and a coarse strainer (19), and a discharge pump (17). The function of the dish-washer is controlled by a control means (24). After a pre-wash-up, washing-up li...

Paper distributing an active compound such as a pesticide or a lachrymatory agent, particularly intended to be used in buildings or closed enclosures. This paper is intended to be burnt to ensure the dissemination of the active compound incorporated in the paper. To ensure an efficient and rapid dissemination by means of a large volume of combustion gas containing only a little smoke and originati...

A frame 4 can be fixed on a manhole framework 2 at ground level. The frame is equipped with a supporting part 7 for a feeding device 8 for a semi-rigid long continuous object F which is to be fed into or drawn out of a duct 3 down in the manhole 1. The feeding in or drawing out is to be carried out from or to ground level respectively. The frame is provided with or can be combined with locking dev...

Through a double-acting screw function, the adjuster moves the press fixture plate (12) to the required level, and by reason of a pre-programmed control earlier adjustments can be reproduced and re-adjusted dependent upon the press material quality and thickness. - The double-acting screw function is based on a right-left hand threaded spindle movement with a sawtooth thread profile (11) which can...

A camera system is installed in the building site crane so that the crane operator can monitor, via a screen, the lifting and handling operations. This can be done in detail so that he can follow the lifting function, and also the ground surface around the point from which the lift is effected. The system is based on a power and picture transmission technique which overcomes all stresses and strai...

In the space defining the circulation circuit is a highly insulating wall plate (8) and an intermediary glass pane (13) of the insulating glass type which are so arranged that an air current can flow upwards on one side and downwards on the other side of the wall plate (8) and intermediary glass pane (13) via channels (17a,17b) in horizontal parts of the window frame (7) and arch (9). The air curr...

The invention relates to a fish-farming device comprising a number of bags lowered into the water. The upper part of the bags is configured with non-water- permeable walls, whilst the lower part allows water to pass through. Fresh water is fed continuously into the upper part and dirtied water is led away from the lower part and up along the outside of the bag.

Once the carriage (1) is in contact with the paper rolls, components retaining them are released so that they rest freeling on the carriage for removal from the machine.
